Work DEPI eMap

Supporting Victorian cross-agency management of bushfire and other natural hazards.


We work alongside the specialist team at DEPI to deliver an operational support system that is vital to the management of emergencies across the State of Victoria.

Managing emergencies

We worked in partnership with the Department of Environment and Primary Industries to develop, maintain and support the award-winning eMap system.

To ensure eMap is a reliable, resilient and powerful tool, we provide technical expertise and advice with the help of cross-agency domain specialists.

We introduced technical disciplines into the maintenance and deployment of eMap which have helped to transition the system from its initial release.

We developed a suite of data management processes that ensure the data presented in eMap is current and have created new tooling in the application to enhance the system’s capability.

Better processes and tools

We introduced a series of processes and tools including Versioning, Continuous Integration and Automated Deployment that help DEPI manage change across eMap safely.

eMap is a large, complex system under constant change. During fire season the system performs a vital operational function. It was very important that we ensured the state of the overall system at any given time was well understood and we were also able to propagate changes to the system in a managed way.

eMap is supported by Geocortex Essentials and ESRI’s ArcGIS Server in a high-availability environment. Changes to all aspects of the system are managed through the Git version control system. Continuous Integration is used together with advanced deployment scripts to allow the system to be automatically updated across all environments, including automatic deployment of all ArcGIS Map and Geoprocessing services.

Automated Data Management

We created a series of services which provide interfaces into the eMap system allowing external systems to access eMap data as well as push vital information into the eMap environment.

eMap is a mapping system that relies on being continually updated with current data. This is especially important when the system is used in an emergency environment when critical decisions must be made on the most accurate and up to date data available.

We exposed a series of geoprocessing services via ArcGIS Server. These services allow specialist teams to push data, such as infrared fire scan images and the output from Rapidfire predictive models directly and automatically into eMap. The data is synchronised across the high-availability eMap environment and can be immediately used to make informed decisions.

Enhanced capability

We have developed a number of features into the eMap system to extend and enhance its capability, including enhanced printing services and tools that assist fire management professionals to approve and publish predictive impact zones.

Printed maps still perform a vital role in emergency management. Being able to quickly and seamlessly move from a digital map to a printed map is important. We used Esri technology to build a print solution that enables users to accurately create large scale printed maps from the web-based eMap system.

The control of information within an emergency is extremely important; field-based observations and automated predictions must be carefully analysed and considered before sharing with wider audiences. We designed workflows and automated data creation and publication processes that allow other agencies to access vital data once it has been approved.

We also provided custom Python modules that are made available through Esri’s ArcGIS Server. These services support both the printing and approval features and are consumed from within Geocortex workflows.


We now work alongside the specialist team at DEPI to deliver an operational support system that is vital to the management of emergencies across the State of Victoria.
